Car Door Seal

Car door seal (also known as automotive door seal, automotive weatherstripping and vehicle door seal) are extruded profiles designed to seal gaps between vehicle doors and bodies, blocking water, dust, and wind noise for a quiet cabin environment.

 

OKIN Rubber uses co-extrusion technology to combine a dense EPDM base with a sponge EPDM bulb, ensuring a firm grip and a soft sealing surface. We offer internal metal carriers (steel or wire) for secure, adhesive-free installation. Our extrusion process guarantees high resilience and resistance to UV, ozone, and extreme temperatures.

 

Compliant with IATF 16949 standards, our seals provide excellent compression set resistance and acoustic insulation, maintaining peak performance under high-speed driving and heavy use. Our automotive seals are ideal for:
  • Passenger & Commercial Vehicles: Primary/secondary door seals, trunks, and hoods.
  • Specialized Transport: Truck cabs, RVs, buses, and agricultural machinery.
  • Heavy Equipment: Forklifts, construction vehicle enclosures, and tractor cabins.

Features of Car Door Seal

Waterproof Seal


Car door seals can effectively prevent rain, snow, and other liquids from entering the interior of the vehicle. It helps protect your car's carpets, seats, and other interior parts from moisture or damage.

Sound Insulation And Noise Reduction

Car door weather stripping can reduce the entry of external noise and improve driving comfort in the car. This is particularly important for drivers who drive for long periods and in noisy urban environments.

Windproof And Dustproof

Car door seal strips can also prevent tiny particles such as sand and dust from entering the car. They help keep the interior of your vehicle clean and reduce the need for interior maintenance.

Heat Insulation


Some car door strips also have a certain thermal insulation function. They help maintain comfort inside your vehicle during extreme temperature conditions.

How to Keep Car Door Seals From Freezing

  • Use antifreeze: You can spray or apply some special rubber antifreeze on the door seal. This helps prevent the seal from freezing in extremely cold weather while maintaining its flexibility.
  • Regular Cleaning: Regularly cleaning moisture and dirt from your door seals is an important step in preventing freezing. Use mild soapy water and a soft brush to clean the seal. Make sure there is no residue on the sealing strip.
  • Use silicone grease or lubricant: Apply some silicone grease or rubber lubricant to the door seal to increase its frost resistance. This makes it easier to stay soft in cold temperatures.
  • Avoid using hot water: When the door seal is frozen, avoid using hot water to thaw it. Hot water may cause the seal to heat up rapidly, and then rapid cooling may result in freezing. This may also damage the seal.
  • Leave a gap when parking: Leaving a little gap in the door when parking can help reduce ice buildup on the door seal. This helps to allow moisture and heat inside the car to escape to the outside, reducing the chance of ice forming.

How to Install Seal on A Car Door

Prepare Tools And Materials

Before you begin installation, make sure you have the tools and materials you need. This includes weatherstripping, cleaners, wipes, measuring tape, scissors, etc.

Clean The Door Edges

Clean the door edges with detergent and a wipe. Make sure the surface is clean and free of grease, dust, or other impurities. This helps ensure that the car door seals adhere tightly and remain stable.

Measure And Cut

Use a measuring tape to measure the length of the door edge. Cut car door seal strips as needed. Make sure you cut it appropriately so it fits the edge of the door.

Test Fit

Before actual installation, place the car door weather seal on the edge of the car door to test. Make sure it's the right length and shape and doesn't prevent the door from opening and closing properly.

Apply Double-sided Tape

Apply double-sided tape on the back of the car door weatherstrip, making sure it is evenly applied. Choose high-quality double-sided tape. This ensures that the weatherstripping adheres securely to the door.

Adhere to The Weatherstripping

Carefully adhere the car door seal weatherstripping to the clean door edge. Make sure it fits snugly against the car door to prevent rainwater from penetrating.

Press And Secure

After the car door weather stripping is pasted in place, press gently with your hands or a pressure tool. Make sure the double-sided tape is fully adhered. It may take some time for the double-sided tape to be fully set.

Wait For Drying

It is best to avoid opening and closing the car door frequently until the car door seal strip is completely fixed. Follow the recommended wait times in the installation instructions.
